Los Angeles, Oct 26 (IANS): Singer Lady Gaga and former US Vice President Joe Biden have teamed up with NGO It's On Us to advocate for accountability and support for sexual assault survivors.

In the wake of the ongoing clamour against sexual harassment globally, Gaga acknowledged via a video on Wednesday that she is a sexual assault survivor and that she understands the trauma that the survivors go through thereafter, reports billboard.com.

Biden called the pop star a "great friend" and "a voice for people who have been forgotten, the people who have been abused".

"She's shown enormous courage. And we want to make it real clear. It's on us, it's on everyone to intervene -- to stop abuse when they see about and when they hear about it, to intervene. No man has a right to raise a hand to a woman for any reason other than self-defence. Ever. Period," Biden said in the video.

Gaga added that it can be "terrifying waking up everyday feeling unsafe in your own body".

"But we're here to remind you that it's important to reach out to someone in your life that can trust and to know that they will be there to help you. There will be someone to listen, because you know what, it's on us," she said.
